My cousin told me about this crazy way to find cheaper airline tickets, and the trick was to buy proxy ipv6 https://spaceproxy.net/en/onlayn-proverka-proksi-serverov-ipv6/ . I didn’t believe it at first, but it actually worked — I saved over a hundred bucks on my last trip just by changing my IP location. The proxy ran smoothly the whole time while I compared different regions. Now I use it every time I travel or plan vacations. It’s such a simple hack but seriously effective.
